Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 46.0 g and its apparent mass when submerged is 3.60 g (the bone is watertight). What mass of water is displaced? mass of water displaced: kg What is the volume of the bone? volume of the bone: m3 What is its average density? average density of the bone: kg/m³ about us privacy policy terms of use contact us help careers

A block of wood with dimensions 60.0 cm × 40.0 cm × 8.0 cm floats on water with 75% of its volume below the surface of the water. While floating on water, how much mass can be placed on top of the block before it is completely submerged? The density of water is 1000 kg·m−3
A scientist is calculating the density of an ore sample. The scien- tist measures that the ore sample weighs 22.4 N in air. When the sample is suspended by a thin light cord and totally immersed in water, the tension in the cord is 14.2 N. What is the density of the ore sample that the scientist calculates. You can assume that any buoyant force from air is negligible.
A scale reads 100 N when a piece of aluminum is hanging from it. What does it read when it is lowered so that the aluminum is submerged in water? The mass density of aluminum is 2700 kg/m^3. Be careful, you are given mass density instead of weight density, and we are using SI units.i need answer in problem sigfig
